Supercritical flow refers to a state of flow in open channels where the flow velocity exceeds the wave speed of gravity waves in that fluid. In this condition, the Froude number, which is a dimensionless number representing the ratio of inertial forces to gravitational forces, is greater than one. This type of flow is significant as it influences flow patterns and behavior, especially when transitioning into different flow regimes, such as hydraulic jumps.
congrats on reading the definition of supercritical flow. now let's actually learn it.
